Magic Question 
25th-Jul-2005 08:27 pm
So one of my players wants to create a magic item that's imbued with a spell-like effect, but the only thing I'm stuck on is how to determine what level that spell-like effect will be cast at and how much it will cost. I'm working with the 3.0 Dungeom Master's Guide. Thanks folks.

How is it used? What effect is it? It all depends on the equivalent spell level, power, activation, and number of uses per day. Maybe more. What exactly do you need from this?

I assume that you know where the tables are for magical item creation in the DMG.

best bet is to find something even remotely simmilar in the dm's guide and base it off of that i play an artificer whth a couple home brewed wanderous items and base them aoff of existing items and figure it out from there. if its a weapon or armor you can use the charts in the dm's guide but wonderouse items are a bit tricky. i have a jacket that gives a plus 4 to intimidation and allows you to demoralise three times a day as a free action as if you had the rage feat. the plus 4 on skills is in the chart then from there we added that cost to bracers of arrow snaring which once a day allows you to use a feat like abilaty and then put a -4 penalty on deplomacy when wearing the jacket to get the other two uses a day "its very creepy looking and a circumstance penalty"
i also have made a haver cloak for our rouge which has one largeer pocket on the inside and2 hidden in the lining ,,

Well if I can make a suggestion...get the 3.5 DMG. ALOT better rules for creating magic items I think.

But in the end it really depends on what it can do...how many times it can do it...what shape it takes. A ring that grants wish once and only once is cheaper then a braclet that can shoot maximum magic missile at will. So it depends on the circumstances.

I know where all the tables are and stuff, but spells are cast at different levels, so when you put a spell-like effect in an item (such as fireball), they're created with a certain casting level in mind right? Well how does this effect cost? Not to mention uses. I'm sure everything is there, but it's very convoluted and scattered all over the place. Eh, I'll eyeball it.

It is hard to give concrete advice without some concrete examples. Either that or I/we'd have to post some really long rambles covering a lot of ground.

The advice so far is what I'd give at general advice. It is what I do for my own stuff, and I make a *lot* of custom magic items.
- Figure out what you want it to do (general terms)
- Find something similar (or a few things)
- Find one or more spells that might relate
- Mix/stir/shake/boil all the ingredients =)

Your example: A fireball item. Yes, the casting level is important. Let's say you want it usable 2 times per day using a command word. Pull up your favorite chart (http://www.d20srd.org/srd/magicItems/creatingMagicItems.htm) and run some numbers. I usually put things into Excel so I can tweak numbers and see the effects.

Fireball is a 3rd level spell (SL3). You need to be at least 5th caster level (CL5). Command word usage is 1800gp.

SL x CL x 1800
3 x 5 x 1800 = 27,000

For uses per day (up to 5), "Divide by (5 divided by charges per day)". I've never liked that wording. If you want more than 5 uses per day, you're actually better off to just make it straight command word. In short:

SL x CL x 1800 x Uses / 5
3 x 5 x 1800 x 2 / 5 = 10,800

Change the uses to once per day:
3 x 5 x 1800 x 1 / 5 = 5,400

Doing multiple powers per item is tricker. Doing indirect abilities is also trickier. Let's say you want some sort of "mage canon". You might use fireball as one of the spells used to craft the item.

Making items can be complicated, but it also gives you a lot of freedom. If you're unsure, post the idea and function and the community will talk your ear off on implementation, cost, etc.
